The gears 29 are fixed to the vertical rotation shaft 27 in the transmission case 28, and the gears 29 are meshed to transmit rotation. An input gear 30 is provided at an intermediate position between the left and right of the transmission case 28, and an upper part of a shaft 31 of the input gear 30 is projected to an upper surface of the transmission case 28 to fix a passive pulley 32. A rotating shaft 33 whose axial direction is parallel to the transfer direction of the seedling growing pot sheet 1 is provided on a side portion of the transmission case 28, and a guide pulley 34 is fixed to the rotating shaft 33. A fixed drive pulley 35 is provided below the guide pulley 34. The drive pulley 35 rotates by the rotation of the motor. A stretchable telescopic belt 36 is provided between the drive pulley 35 and the passive pulley 32 via the guide pulley 34. Hang around.

An arm 38 protruding rearward is formed at a rear portion of the transmission case 28, and a rear end of the arm 38 is rotatably attached to the upper cleaning pipe 22. Rotating rollers 39 projecting sideways are provided on both front sides of the transmission case 28, and the rotating rollers 39 are brought into contact with the outer periphery of the cam wheel 40. A concave portion 41 and an inclined portion 4 are formed on the outer periphery of the cam wheel 40.
When the cam wheel 40 rotates, the inclined portion 42 moves the rotating roller 39 upward to rotate the transmission case 28 upward around the upper cleaning pipe 22, and the vertical rotating brush portion 2 is rotated.
6 is moved upward from the pot 3, and then the rotating roller 3
When 9 enters the concave portion 41, the front end of the transmission case 28 moves down, and the vertical rotating brush portion 26 fits into the pot 3.

In this case, the cam wheel 40 does not move upwardly so that the vertical rotating brush portion 26 comes out completely above the pot 3, and the lower end of the vertical rotating brush portion 26 is fixed to the seedling growing pot sheet 1.
Is slidingly brought into contact with the next pot 3 while sliding down the upper surface of the pot. Further, the transfer speed of the seedling raising pot sheet 1 and the vertical speed of 26 are synchronized, but 26 is also juxtaposed also in the transfer direction of the seedling raising pot sheet 1 so that the juxtaposed 26 overlaps with the pot 3. Alternatively, the number of times 26 fits into one pot 3 can be changed by changing the transfer speed of the seedling raising pot sheet 1 and the vertical speed of 26, and can be changed arbitrarily. 44 is a mounting shaft for the rotating roller 39, and 45 is a mounting shaft for the cam wheel 40. Thus, the horizontal axis rotary cleaning brush 24 and the pot cleaning brush device 2
5 is provided on the front side with a pair of upper and lower cleaning pipes 46 and 47, and on the front side of the cleaning pipe 46 and the cleaning pipe 47, a discharge-side ratchet wheel is provided. 49 is a drain, 50
Denotes a space formed below the bottom plate 15, which houses a water storage tank, a pump, a motor (variable speed motor) and the like, although not shown. Reference numeral 52 denotes a shaft of the feed-side ratchet 20, and reference numeral 53 denotes a mounting horizontal shaft of the drive pulley 35.

[0013]

Next, the operation will be described. When the used soiled nursery pot sheet 1 is supplied to the transfer stand 6, the nursery pot sheet 1 is used.
The seedling-raising pot sheet 1 enters the washing chamber 16 from one supply port 17 on one side of the seedling-raising pot-sheet washing device 11 and is transferred therefrom. The projection 19 of the supply side ratchet 20 is engaged with the engagement hole 4,
The seedling-raising pot sheet 1 is further transported, receives a spray of a cleaning liquid from an upper cleaning pipe 22 on the upper side and a lower cleaning pipe 23 on the lower side, and a rotating horizontal rotating brush provided on the outer periphery of the lower cleaning pipe 23. 24 cleans the lower surface of the seedling raising pot sheet 1.

Next, the rotation from the motor is transmitted to the driving pulley 35, the telescopic belt 36, the passive pulley 32, the shaft 31, the input gear 30, the gear 29, and the respective gears 29, and the vertical rotation shaft 27 rotates to rotate vertically. The shaft rotating brush portion 26 rotates, and the inclined portion 4 of the cam wheel 40 rotated by the motor.
2 moves the rotating roller 39 upward, and when the end of the inclined portion 42 passes through the lower surface of the rotating roller 39, the rotating roller 39 is rotated.
Falls into the recess 41, the transmission case 28 rotates up and down around the upper cleaning pipe 22, and the vertical rotation brush portion 26
Enters the pot 3 of the seedling raising pot sheet 1 being transferred from above while rotating, and then moves upward while rotating to wash the inside of the pot 3.

In this case, the height at which the vertical rotating brush portion 26 moves upward is set so that the lower end of the vertical rotating brush portion 26 does not completely fall out of the pot 3 and stays in the pot 3. The vertical axis rotating brush portion 26 not only cleans the inside of the pot 3 but also the thin plate 2 of the seedling raising sheet 1.
Is also slid and cleaned, and then fitted into the next succeeding pot 3.

The relationship between the driving pulley 35 and the passive pulley 32 is as follows.
2 and fixed on the side, the passive pulley 32
Is attached to the transmission case 28 and moves up and down, so the distance between the driving pulley 35 and the passive pulley 32 varies, but the telescopic belt 36 is stretched between the driving pulley 35 and the passive pulley 32. , Passive pulley 32
The difference in the distance due to the vertical movement is absorbed by the expansion and contraction of the elastic belt 36, and the rotation is reliably transmitted to the passive pulley 32.

In this case, the passive pulley 32 is provided on the vertical rotation shaft 27 provided on the transmission case 28, and the driving pulley 3
5 is mounted on a mounting horizontal shaft 53, and between the driving pulley 35 and the passive pulley 32, there is provided a guide pulley 34 for rotating the horizontal shaft.
Is provided, the telescopic belt 36 expands and contracts between the driving pulley 35 and the passive pulley 32 and the guide pulley 34, so that the direction of expansion and contraction does not always largely deviate from the axial direction of the driving pulley 35 and the passive pulley 32. The belt 36 does not come off.

The seedling-raising pot sheet 1 whose lower surface is cleaned by the horizontal-axis rotating cleaning brush 24 and whose upper surface and the inside of the pot 3 are cleaned by the pot cleaning brush device 25 is
The finish is washed by the cleaning liquid from the cleaning pipe 6 and the cleaning pipe 47, discharged from the other side outlet 18, further transferred to the front side by the transfer table 6, and taken out from the cleaning chamber 16.

[0019]

According to the present invention, a seedling raising pot sheet 1 formed of a thin plate 2 of synthetic resin and formed with a large number of pots 3 at predetermined intervals in the front-rear and left-right directions, and the sheet 1 is supplied from one side supply port 17. A washing chamber 16 having a fountain mechanism inside the outlet from the other side outlet 18, a transmission case 28 which moves up and down by rotation of a cam wheel 40 provided in the washing chamber 16, and a passive pulley attached to the transmission case 28 side 32, and the transmission case 28 attached to the transmission case 28 side moves downward and fits into the pot 3 from above, and moves upward when the transmission case 28 moves upward and the rotation is transmitted from the passive pulley 32. In the one comprising the rotating brush part 26, the seedling-raising pot sheet washing in which an elastic belt 36 is wrapped around the passive pulley 32 and a position fixed drive pulley 35 provided at a desired position. Since it is obtained by the device, the vertical axis rotation brush unit 26 up and down relative to the pot 3 with a simple structure
The rotation can be transmitted to the pot 3, so that it can be moved up and down with respect to the pot 3 while rotating the vertical axis rotating brush portion 26, the inside of the pot 3 can be surely cleaned, and the cleaning work required for reusing the seedling raising pot sheet 1 is extremely difficult. Easy to do.
